If I were to get a 357SIG barrel for my 23, what barrel would you guys recommend? I know LW makes a low-priced one. What are the thoughts? Should I spend a few bucks more and get something different?

I bought the stormlake g32 barrel for my g23 first. So far its been flawless. It has just a little bit tighter chamber than stock. The only difference other than rifling imo is the stock barrel has a good smooth finish with rounded edges. I just bought a factory sig barrel and so far it has shot great also. I plan to cc the factory barrel and only shoot jacketed bullets in it. As for as Lw barrels I've never had a problem with the 40 and 45 barrels I've bought from them except for the shorter chambers which should not apply in 357sig.

Well, here's something to consider...my buddies g32 stock bbl seemed to be fully supported (bottleneck advantage). That would be your most reliable option, as you would know. Second to that, if you are looking for the tighter than stock chamber I'm thinking Storm Lake might be the way to go. Seems their quality is consistent from what I've seen around the forums and the price isn't bad.

Is there a .40 barrel that is supported, and reliable as stock? Or is support at the expense of reliability in the .40?

The .40 Glock barrels made within the last 10 years or so are supported pretty well and are reliable. Some of the aftermarket barrels do have slightly better support by not adding as much chamfer around the feed ramp and entrance of the chamber. There is usually some tradeoff.

The .357sig and 9mm Glock barrels are better supported than the .40. I have not have any issues with the Glock barrels and they are quality piece so that is what I use. Whenever I pick up a G24 I will either pick up a Storm Lake, KKM or Barsto .357sig barrel for it because Glock doesn't make any 6" .357sig barrels for it. Wish they did.

Using factory SAAMI spec rounds, there never was a problem. There has been continual refinement, but not resulting from rampant failure from spec rounds. Older barrels were quite adequate, but not as able to compensate for overcharged rounds or reloaded brass. I've owned and been issued .40 glocks since they came out, and despite heavy agency and personal shooting, never encountered or observed a problem.

EXACTLY!!

The problem was never so much the chamber support as with the ammo. The early Federal cases marked "FC" usually being the culprit. They have long since been withdrawn for the most part, except for a few residuals scattered sporadically in the hands of non LE. There is no such thing as 100% chamber support outside of a revolver as well.

FWIW, I have a new Glock Gen 4 OEM .357 SIG barrel I play with in a Gen 4 G23 and it is superb. To be frank, it shoots just as good as my p229 in .357 SIG.
